It actually worked!

I used this product to stop a coolant leak at the timing cover on a Chevy Trailblazer with 250K miles. It was buttoned up tight in an hour with no cooling system side effects. Worked great for me. Just follow the instructions. I did hear a rumor that this product was used to stop a leak in the reactor cooling system in the nuclear submarine Nautilus...so I figured if it was good enough for them, I'd try it in my car. I'm glad I did.

NO MORE LEAK!

I had a lingering coolant leak that was getting bigger over time. My friend suggested these tablets since they are easy to use for someone who doesn't know about cooling systems. I drove the car around for about 30 minutes that the next morning my driveway was dry! I intend to use this every 15,000 miles or so to keep the leak at bay.

This brand is my go-to for leaks

Works quickly and directions are simple. Used this in a few cars in the past - most recently a Jeep Grand Cherokee, and previously an old Nissan Altima. Both times the leak was sealed and it lasted until I no longer had the cars. This is the go-to brand for sealing leaks. Easy and way more affordable than a dealership.
